A6100 installation issue

So, this is the 2nd adapter I got today, thinking the one from yesterday was malfunctioning. I even tried to reset the USB port, but couldn't figure out how to without an error message. I keep getting the message, "Insert the wireless USB adapter into your computer. Click OK to continue." When I do, it repeats the message until finally it says the computer can't find the A6100 adapter on my computer. I tried disabling the permission for components with manifests and checking my devices (it wasn't listed). I have a Dell with Windows XP. Isn't that compatible?
